This file is an emulation of the GLCD interface using the

new GDISP interface. It is probably not a perfect replica,

some code changes may be necessary.
|

Note it does not replicate the GLCD low level driver, just
|
|
the high level interface.
|
|
You may also need to define the various GDISP_NEED_XXX in your
|
|
halconf.h in order to turn on the functionality you need.
